PDL::GSLSF::FERMI_DIRAC.3pm

NAME

PDL::GSLSF::FERMI_DIRAC - PDL interface to GSL Special Functions

DESCRIPTION

This is an interface to the Special Function package present in the GNU Scientific Library. Please note that:

Complete Fermi-Dirac Integrals:

  F_j(x)   := 1/Gamma[j+1] Integral[ t^j /(Exp[t-x] + 1), {t,0,Infinity}]
 
 

Incomplete Fermi-Dirac Integrals:

  F_j(x,b) := 1/Gamma[j+1] Integral[ t^j /(Exp[t-x] + 1), {t,b,Infinity}]
